Body pingo

A rule in beer pong originating from the UK and heavily practised in Australia and New Zealand. If your opponents are on the last cup, you throw the ball, and hit them somewhere on the body while they are drinking, this counts as three cups removed.

Oh my God I just got body pingoed and lost!
